Perioperative outcome of Whipple's procedure with special attention to the impact of preoperative biliary drainage: a real-life scenario

The aim of the present study is to report the overall perioperative outcome of Whipple's procedure (WP) with particular attention to the impact of preoperative biliary drainage (PBD) on postoperative clinical outcome. All the patients who underwent WP at our institution between August 2007 and December 2019 were retrospectively reviewed. Impact of PBD and the stent-surgery interval on the postoperative clinical outcome of WP were analyzed. Of the total 404 patients, 254 (63%) were male. The median age at operation was 50 years. The overall morbidity was 57.7%. The most common complication was surgical site infection (SSI) (28.7%). POPF developed in 57 (14.1%) patients. Delayed gastric emptying, intra-abdominal collection, and postpancreatectomy hemorrhage developed in 82 (20%), 23 (5.7%), and 18 (4.5%) patients, respectively. PBD was performed in 175 (43%) patients. The median stent-surgery interval was 59 days. Postoperative overall complications and SSI were significantly more common in PBD patients. No significant difference in postoperative major complications or mortality was observed between PBD and no-PBD patients. Stent-surgery interval more than 6 weeks was not associated with increased postoperative complications or hospital stay. Similarly, PBD solely based on serum bilirubin >= 15 mg/dl has no beneficial effect on surgical outcome. The operative mortality was 4.2% (n = 17). The median postoperative hospital stay was 13 (7-68) days. PBD is associated with increased incidence of postoperative overall complications and SSI, but does not affect major complications or mortality. PBD-surgery interval greater than 6 weeks does not have a negative impact on postoperative clinical outcomes.
